MOTOR-VEHICLE CONSTRUCTION.

To all whom t may concern:

- Be it known that I, HARoU'rIUN K. Kon- YOUMJIAN, a subject of theSultan of Turresiding at Cleveland, in the county of Cuyahoga and Stateof Ohio, have invented certain new and useful Improvements inMotonVehicle Construction, of which the following is a specification.

This invention relates generally toinotor vehicle structures andparticularly to the cooling system for the engine and 'to the electricgenerating plant.

AMore specically, the invention relates to a combined radiator coolingfan and electric generator, arranged in a single unit whereby the driveof the fan serves as a drive for the generator, and further where- -bythe presence of the generator in the fan is utilized to increase theefficiency of that factor and the presence of the fan bladesabout thegenerator, increases the efficiency of the generator by maintaining thelowest possible temperature for the generator in the hood of the car.

rIhe invention may be further briefiy summarized as consisting in theconstruc-` tion and combination of parts hereinafter set forth in. thefollowing description, drawings and claims vReferring to the drawings,Figure 1 is a perspective view, of a portion of a motor vehiclx engineand radiator, showing my iinproved radiator cooling fan and generav1erin piace; Fig. 2 is a side elevation partly in section showing thedevice, and Fig. 3 is a detail'view of the field magnet.

I carrying out the invention. any preferred form of construction ofmotor 'vehicle may be arranged according to my invention, provided itpossesses the necessary characteristics, but I have shown onearrangement in the drawings wherein 1 represents a suitable engine, 2 aradiator, and 3 the driving pulley, driven o v the engine and arrangedto drive, with a suitable belt 4, the combined cooling fan andgenerator, to be described.

Mounted upon the frame of the engine is a suitable supporting bracket 5,carrying a fan supporting member 6, which is adapted to receive thethreaded end 7,- of a hollow supporting shaft 8. This shaft carries atits outer end a field magnet, comprising a central core 9, a winding 10,and field frame members 11,'and 12, which are ar- Specication of LettersPatent.

ranged at opposite ends of the core '9, so

that the pole pieces are interspersed about the periphery Vof thewinding The pole pieces are bored out to receive insulating tubes 1l,which receive carbon brushes l5, normally pressed outward by means ofsuitablel springs 1G. The brushes extend out on one side of the magneticfield as shown.

Rotatably mounted on the hollow shaft 8 and preferably by means of ballbearings 17 and 18 is a casing sleeve 19, carrying a driving pulley E20and a casing member 21, extending over the field magnet. Secured in theback ofthe casing is a suitable commutator '29., provided withcomuniadapted for engagement by the brushes 15. Secured within the casin21, is a laminated armature 24, provi ed with suitable windings 25. Inconnecting thel generator, suitable leads not shown, are led through thehollow shaft and are connected to the proper brush holders, like brushholders being connected together. A field winding is then connected as ashunt winding. rI`he commutator segments are connected in any suitablemanner not shown -to the armature winding.

Secured to the periphery of the casing 21,

are suitable fan blades Q6, which are adapted to draw air through theradiator. The casing 21, is also provided with a cover 27, secured tothe front thereof in any suitable manner, as by bolts 28, passingtherethrough reason of this construction, the combination of thegenerator and cooling fan increases the efficiency of both factors,since the generator prevents a back draft through the centervof the fanand the fan blades produce a circulation of air about the gene erator.

Having described' my invention, I claim:

1. In combination with the chassis of a motor vehicle including theengine and radiator, of a combined radiator cooling fan and generato?unit mounted beween .the en gine and radiator and including a geneieoi.and fan blades amnged #Lo-rotate with the mountedon said Chassis at thefront of the engine7 and a driving pulley at the inner:l

end of said unit. close to said support.

2. In combination with the chassis of a motor vehicle including theengine and mdiator, of :i combined radiator cooling; fan and generatorunitn mounted hemelen lille en @gine @nel aflin'sof: @nel ineluding egenerator @nifl an blades airzinged toroate Wien the olsary elenien;olf' the generaor, said unit being supported solely at one @ncl which isnext to the engine, a support foi' said unit at the front of alle enginebut independent of `the letter, and a driving pulley at the inner end ofthe Seial unit-close to Said support.
